According to ProStores’ message board, an unplanned, system-wide outage took place on Tuesday, May 28. The cause was said to be a third party vendor of data services. The issue lasted for hours and affected all merchants and tech support lines.
At 3:00PM Tuesday, ProStores reported, “We’ve identified and resolved the problem and are taking steps to ensure that it doesn’t happen in the future.” But within 30 minutes, a second outage occured; and was “related to the first.” The second outage took nearly five hours to resolve.
As a courtesy, successful transaction fees will be refunded to ProStores merchants for the month of May. This exposes one shortcoming of multi-tenant software. A service glitch at the data or application layer can affect everyone all at once.
